The essays in this section focus on the relevance of archaeological comparisons for discussing the anticipated difficulties with communication between humans and aliens. "A Tale of Two Analogues" by Ben Finney and Jerry Bentley draws on Finney's studies of Mayan culture. They draw comparisons between the protracted process of translating Mayan works and the difficulty of translating an alien work, and cast doubt on the views of some mathematicians and natural scientists that an extraterrestrial civilization would communicate with humanity solely through the "universal language" of mathematics and science. The second essay, "Beyond Linear B" by Richard Saint-Gelais, analyzes potential alien communication through a semiotic lens, commenting on the issues involved in interpreting the signs and symbols of a fundamentally different culture. He notes that the issues faced in semiotic challenges such as decoding an unknown human language may be even greater for an alien language. For instance, he describes how all known writing systems for human languages are either alphabetic, syllabic, or ideographic, and anthropologists are able to estimate which type an unknown system is by its number of characters, which may not be a shared assumption for an extraterrestrial writing system. "Learning to Read" focuses on the hypothetical alien translation of interstellar messages transmitted by humanity. Its author Kathryn E. Denning deems the task of writing alien-translatable messages "neither trivial nor impossible", considering it a difficult task but one worthy of study; she discusses the need for interdisciplinary study to produce such messages, with important work from fields such as cryptography and anthropology. She also discusses the polarized views of natural and social sciences on the issue of alien translation, with natural scientists tending to take far more optimistic perspectives of the ease of translation than social scientists. "Inferring Intelligence" by Paul K. Wason describes the difficulty of understanding the work of prehistoric cultures and compares this difficulty to that of understanding the work of extraterrestrial cultures. He refers to the controversy regarding the meaning of Paleolithic cave art, as well as the relative recency of identifying stone tools as the intentional productions of intelligent beings.
==== "Anthropology, Culture, and Communication" ==== John W. Traphagan has two essays in this section, "Anthropology at a Distance" and "Culture and Communication with Extraterrestrial Intelligence". In the former, he draws comparison between the "anthropology at a distance" practice of anthropologists in the early nineteenth century, who often lacked the resources to perform fieldwork with the societies they studied, and the practice of SETI in discussing and studying uncontacted extraterrestrials. The latter focuses on the concept of hypothetical "universal languages", such as music or mathematics, and the differences human and alien cultures may have in their interpretation of these languages. "Contact Considerations" by Douglas Raybeck considers human-alien interaction through comparison to terrestrial colonial interactions. He gives the specific examples of European contact with Aztec, Japanese, Chinese, Iroquois, and Māori cultures, all five cultures being politically and technologically complex at the time of first European contact. He discusses the likely significance of trade to human-alien interactions, both for goods and services exchanged in trade between human cultures, but potentially also for things such as music that may not exist in an alien culture. In "Speaking for Earth", Albert A. Harrison discusses the development, longevity, and potential consequences of projecting interstellar messages. He takes an optimistic position of the benevolence of extraterrestrial civilizations, referring to his own anthropological research that shows societies that endure for long periods tend to be more peaceful and less aggressive. Harrison supports Active SETI, the process of actively transmitting messages from Earth to potential interstellar societies, and discusses planned and actual attempts at it.
==== "The Evolution and Embodiment of Extraterrestrials" ====
Vakoch's chapter, "The Evolution of Extraterrestrials", focuses on hypotheses of what an alien intelligence would look like, such as whether it would be humanoid or nonhumanoid. He discusses how as early as The Celestial Worlds Discover'd, published by Christiaan Huygens in 1698 and one of the first works to consider the lives of extraterrestrial beings, the possibility was raised that aliens would have similar body plans to humans (such as walking upright) but look radically different within such confines. Both arguments in favour of convergent evolution to a functionally humanoid form and divergent evolution to a radically inhuman form are summarized and considered. "Biocultural Prerequisites for the Development of Interstellar Communication" by Garry Chick discusses the Drake equation, a means by which to estimate the number of extraterrestrial civilizations in the Milky Way galaxy capable of communicating with humans. Referring to statements by figures such as the author Michael Crichton that the parameters in the Drake equation are unknowable, and that this casts foundational doubt on the validity of SETI, Chick aims to narrow the range of possible estimates for these parameters. In "Ethology, Ethnology, and Communication with Extraterrestrial Intelligence", Lestel considers the philosophical definition of 'communication' in the context of human-alien contact. He holds that contact between terrestrial and extraterrestrial societies would have traits of both ethnology, the study of other human cultures, and ethology, the study of animal behavior. In the book's final essay, "Constraints on Message Construction for Communication with Extraterrestrial Intelligence", William H. Edmondson summarizes the issue of designing messages to be understood by extraterrestrial societies. He notes the assumptions involved in constructing interstellar messages, such as that aliens will have senses and that aspects of cognitive function (e.g. intentional behavior) will be shared between all intelligent organisms.
